The MPX-1 has in input level switch to choose between Unbalanced (8 dBu to -14 dBu) and Balanced (+20dBu to -2dBu). I am using the inputs unbalanced at the higher sensitivity, patched from my mixer effects sends. I suppose I could switch to the lower sensitivity, but the MOTM outputs are unbalanced. Shouldn't matter if the ring lug gets grounded by a patch cord, right? The outputs are +18 dBu at max scale. I'll just have to try it. The only thing I did with the MIDI on the MPX-1 was hook it to my keyboard MIDI out. But I did not try using it as a controller for the MOTM-650. I'll try that too. Thanks for the ideas. -Richard Mark wrote: > While I don't own an MPX-1 myself, as far as I can remember, it has > both input and output level knobs, and -10/+4 switches in the back. > So I don't think you would need any any sort of I/O module.
